[New technic of the transjugular cava blocking in the removal of acute pelvic vein and inferior vena cava thrombosis].

Thrombosis of the inferior vena cava rarely occurs. However, it mostly develops by continous growth from thrombosis of the deep leg and pelvic veins. Thrombus formation in the inferior vena cava carries a potentially lethal risk because of possible involvement of the renal veins with consecutive renal failure or development of fulminant pulmonary embolism. Therapy of choice consists in early diagnosis and immediate thrombectomy. Choice of the operative procedure is of the utmost importance for immediate and late results. Our technique consists of inserting a balloon catheter via a side vessel of the internal jugular vein and placing it into an infrarenal position, where it is blocked, thereby preventing blood flow from the area to be cleared. Three cases in which this technique was employed are presented.
